TO ALL WHOM 'IT MAY CONCERN:

Be it known that I, SIDNEY B. SILL, of Three Rivers, in the State ot'Michigan, havenvented certain new and useful Improvements inHeat-Radiators; and I hereby declare that the following is a true, full,and exact description of theesame, reference being had to theaccompanying drawings, and to the letters 'of reference Lmarked thereon.In the annexed drawings, which make apart of this speciiication- Figure1 represents a central vertical section oi' my radiator.A

Figure 2 is a'plan view of the same.

Figure 3 is a plan view ofthe radiator when reversed.

The body of the radiator consists of drum, A, furnished attop vwithcollar C, and at bottom with the adjustable chamber B. D represents anoval flue, extending from the top of collar Cdownward to alittle morethan halt' the length of drum A. The said flue D can be raised orlowered by means of the knob 7c (see fig. 1;) Into the top of chamber Bis adjusted the metal plate m, which, after extending sufficiently farto cover about three-fourths of the inner circumference of B,-isconnected with and fastened to the vertical plate n. Into plate m acircular opening is made, with a rim aroundit, through which lthe rod iis made to pass, the said rod being soldered to damper G. The damper G,when turned in a horizontal position, is designed to close the openingin plate m, and thus prevent the products of combustion from ascendingthrough the flue D. S represents a thin metal plate, curved at its outeredge, and soldered to the upper end of plate n in a horizontal position.The object of plate S is to ill up the space between the plate n, andthe inner circumference of flue D, and thus prevent any ofthe productsof combustion from entering the flue D.

My radiator affords four modes of radiation: first, from the chamberbelow the valve G; then from the Exed side tluc between the plate n andthe circumference ci' drum-A thirdly, the chamber above the valve G, andbetween the oval flue D and drum A; and lastly, the chamber in the ovalflue D. I Having thus described my invention, what I claim, and desireto 'secure by Letters Patent, is-'- 1. The adjustable chamber B, whenfurnished with valve G, vertical plate 1t, combination with flue D, thewhole constructed and operating as set forth.

2. The four radiating-chambers, arranged in the -manner and for thepurpose specified.'

In testimony that I claim the above, I hereby ax my signature inthepresence of two witnesses.
